' -zen' ofthe United States, residing at thecity of \Vorcest'e'r, in the county of" VVorce'steI" and. State. of' hfassachusetts, have invented new an'clnsefi'il Improvements in Radiators, offwhich thefollowingis a specification;

This invention relates to imp-rovements in heaters or radiators and has for its object to provide a simple, inexpensive andlhighly eflicient device of-this'character'; One of the objects of my invention is to provide means for spreadingheet rays about a room directly from-a stove pipe connected with a: regnlhi" heater or'st'ove and in such a manner as to permit th'ehot' fumes elnanat ingv from. the stove and escaping, to thechimney to heat it larger surface of the stove pipe than has hitherto been the case.

The principal object ofniy invention is to provide emdfia'tor which may be coupled secunelyon a stove pipe 01% between the sections thereoi this type of; radiator spieddimg the heat rays, in directions sons to heat a lai'geii ai'teathan is possible Without its escape, the escaping products oi coin bastion fi'om the stove; effecting the heating openatlon.

Iii tl1e 'di'2uvings which are merely illustrative'ofmy invention my heater ori'adiaitoi comprising one 01' more siinilir units each ofwhich con'ipo'sed ofthe conical sec tions A and B having' then base edges seotiled together, thuspfovidin'g a snlostul tially tnhulzn body tztpe'ringto narrowin op po'site directions from its center. The upefen'd' of this bodjv 1 has a nipple, the central bulged o'ut' portion of this body being designated 2, and Where the base edges of sections" A and B shut is designated 4-. Thete'is a coll'zif 5 having a flaring flange 6' secured to tlie'fiusto-con'ical section A and to which z'uiy section ofa stove pipe may be attached; A hollow deflector consists of the two finsto-conie'al members 24' and 25 seci'n'ecl together at their base edges and formed with the ports 26. Secured to the conical section 24? of this deflector circumferentially thereof are the angular lugs 23 secured by suitable fasteners thereto and formed upon the hanger straps 21 the upper ends of which straps are inclined to form lugs 22 secured to the inner walls of the upper conical section A. These hanger straps are bridged across the space between the conical sections of my heater and the deflector and serve to hang and support this deflector concentrically within my heater to provide sides inclining in the same general direction but at somewhat different angles with respect to the axis of my heater. This deflector is of a smaller diameter than the heater and is also of a lesser-height and its upper and lower ends are spaced respectively from the upper and lower ends of the heater. With this arrangement, the annular passage provided between the deflector and the heater sections is of reduced cross section near the middle of the heater.

It will be seen that when my heater isconnected as a pipe section to a stove pipe and the hot products of combustion rise to escape thru the chimney the gases will initially expand upwardly and heat the wall of section B of my heater being spread out by the adj acent walls of the deflector and some of the gases will enter thishollow deflector thru ports 26 so as to heat the interior of this deflector. The products of combustion will thereupon be deflected and reduced in volume towards the central portion of the heater so as to impinge all around the section 24 of the deflector and from there expanding and emerging thru the nipple 1 to thechimney and atmosphere.

Figure 1 shows a tier or bank of my heaters connected to a stove pipe and in this event it is desirable to bring the heaters as closetogether as possible so that a suitable coupling to connect them together is desirable. I provide this in the form of two templates or collars 11 and 13, formed conical and secured around the narrow conical ends of the confronting sections A and B of two heaters, these collars being formed with integral pipe portions 10 and 12 having their edges abutting together, and if desired these edges may have a tongue and groove fit as shown in Figure 13 where the annular tongue 15 of one section fits in the corresponding groove 14: formed in the other section. In order to lock these sections together integral lugs 19 are formed around sections 10 and 12 in such a way, as shown in Figure 15, that the lugs of the upper section incline or extend downwardly while those of the lower section incline or extend upwardly both sets of lugs being formed with holes through which bolts project so as to clamp the coupling sections together. It will be seen that when the pipe sections 10 and 12 are fastened together the radiators A, B will be connected in alinement having intervening pipes formed between them, the latter making a good flame and smoke tight joint with said radiator sections. The clamping bolts are designated 18 and have binding nuts 20 thereon. Fasteners 14E secure the collars 13 and 11 to the sections A and B of adjacent heaters passing thru the holes 11 formed in these collars.

Numerous modifications may be resorted to in practice without departing in principle from the details of construction herein disclosed.

What I desire to secure and claim by Letters Patent is 1. A radiator of the class described, comprising a pair of frusto-conical sections having their base edges secured together, and a deflector supported concentrically within said sections, and spaced therefrom, the said deflector also consisting of frusto-conical sections having their base edges secured together, with the sides of said deflector sections inclined in the same general direction as the sides of said heater sections, but at.

different angles with respect to the central axis of the radiator, whereby the annular passage between said sections is of reduced width near the middle of the heater. 7

2. In combination with a conical tubular member, a tubular coupling having a flaring flange secured around the lower end thereof, a downwardly inclined integral lugformed upon said coupling and having a hole therein, a tubular coupling having its edge brought together with the edge of the other tubular coupling and also formed with an upwardly extending lug having a hole therein, and means passing thru both holes and clamping both couplings together. i

3. A coupling for radiator sections con-. sisting of a pair of tubular portions formed with flaringcollars for attachment to the radiator sections and having their edges brought together, a series of circumferentially spaced lugs respectively inclining upwardly and downwardly and abutting one against the'other, and bolts engaging the pairs oflugs and clamping them together.

t. In combination a pair of tubular frusto-conical members having their inner narrow portions confronting, a pair of conical sleeves secured tothe last named portions and having pipe sections held in abutting relation, lugs carried by said respective pipe sections in abutting relation, and means for clamping said lugs together. 7
